Hi,
Maybe have you find the answer to your question since, but if not, this is a way to do what you want.
I have found the explanation to do it on this two pages in Harris documentation:
http://www.harrisgeospatial.com/docs/Creating_Menus.html
https://www.harrisgeospatial.com/docs/widget_tree.html
You have also access to several examples in examples/doc/widgets subdirectory.
;-------------------------------------------------;
; Manage context_menu event
pro context_event_Handler, event
WIDGET_CONTROL, event.ID, get_value=value
case value of
'button1': BEGIN
print,'button1'
END
'button2': BEGIN
print,'button2'
END
endcase
end
; Manage classical event from the widget
pro test_treecontext_event, event
; Test for context menu events
IF (TAG_NAMES(event, /STRUCTURE_NAME) EQ 'WIDGET_CONTEXT') $
THEN BEGIN
; Obtain the widget ID of the context menu base.
contextBase = WIDGET_INFO(event.ID, $
FIND_BY_UNAME = 'contextMenu')
; Display the context menu and send its events to the
; other event handler routines.
WIDGET_DISPLAYCONTEXTMENU, event.ID, event.X, $
event.Y, contextBase
ENDIF
end
pro test_treecontext
tlb= widget_base(/column)
tre_bs= widget_tree(tlb, /no_bitmaps, /expanded, /CONTEXT_EVENTS)
tre_fo= widget_tree(tre_bs, /folder)
tre_s1= widget_tree(tre_fo, value='Size 1') ;need context Menu
tre_s2= widget_tree(tre_fo, value='Size 2') ;need context Menu
tre_s3= widget_tree(tre_fo, value='Size 3') ;need context Menu
contextMenuB = WIDGET_BASE(tre_bs, /CONTEXT_MENU, $
UNAME="contextMenu")
button1 = WIDGET_BUTTON(contextMenuB, value='button1', $
event_pro='context_event_Handler')
button2 = WIDGET_BUTTON(contextMenuB, value='button2', $
event_pro='context_event_Handler')
widget_control, tlb, /realize
; Handle the events from the GUI.
XMANAGER, 'test_treecontext', tlb, /NO_BLOCK
End
;-------------------------------------------------;
